Induction of liquid-crystallinity in molecular clips by binding of different guest molecules

Abstract

The use of clip molecules based on diphenyl- and dimethyl-glycoluril as building blocks for liquid-crystalline materials is described. The synthesis is performed by an esterification of hydroxy-derived clip molecules with trialkoxybenzoyl chloride. 1H NMR titrations show that these molecules, despite the steric crowding, are still able to bind guest molecules in the cleft. The clip molecules show no liquid-crystalline properties, except those based on dimethylglycoluril. However, clips with alkyl chains of at least ten carbon atoms display liquid-crystalline behaviour upon binding of guest molecules, which can be tuned by the substituent of the guest molecules.
